Just bought this Florida boat two months ago. Apparently owner did not service or take care of it as he claimed. After buying I found out the dip stick was stuck and milky tan oil. Mercruiser cruises at slow speed OK. Good water temp and oil pressure on gauges. When bringing it up to a higher speed, begins to lose power & knocks. Conks out after backing off and then will barely turn over.
I have replaced lifters, replaced carbuerator, got rid of old gas and filters, new impellor pump. Tell me what to check or do next.
